Progress in marine geological experimental testing technology and research

Experimental testing is at the forefront of data acquisition and plays an important role in accurately supporting scientific studies. It is an important component of marine geological work. In recent years, with the vigorous development of China's marine geological survey, the Qingdao Institute of Marine Geology has established a comprehensive experimental testing laboratory with relatively complete professional disciplines in distinct marine characteristics. The testing projects cover over 10 scopes, including inorganic chemical analysis, organic chemical analysis, detrital mineral identification, thin-section identification, quantitative analysis of clay minerals, particle size analysis, stable isotope analysis, radioactive isotope dating, luminescence dating, microfossil identification, and core management. To integrate technologies and services in new fields of natural resources, ecology, environment, and agriculture, the laboratory combines the testing tasks and research data from scientific projects from all-range surveys on deep-sea, polar, and natural resource to explore and reform innovative mechanisms, having published many high-level papers and achieved innovative patents, and meeting the new requirements from analysis and testing in marine basic geological surveys, marine mineral resource surveys, and marine environmental geological surveys.
